CHLOROFQRM-DRQPPER.

Speciflcatiop of Letters Patent. Application filed October 12, 1905. Serial No. 282,386.

Patented June 12,1906.

To all whom it may concern.-

Be it known that I, FREDERICK WACHTER, a citizen of the United States of America, and a resident of Jersey City, in the county of Hudson and State of New Jersey, have invented certain new and useful Im rovements in Ohloroform-Droppers, of whlch the following is aspecificatlon.

This invention has reference to improvements in liquid-fluid droppers, and pertains particularly to a novel chloroform-dropper;

Ohloroform and other light and easily volatile liquids which are used as anesthetics and anody'nes are generally dispensed in small uantities, preferably op by drop. This is done in order to volatilize and diffuse the anesthetic freely and rapidly in the atmosphere and to apply to the patient a minute quantity onl at a time. For the purpose of accomplis g this the anesthetlcs are dlspensed by means of drop ing devices from which the liquid flows in ops. These liquids are speclfically light, thin,- and very mobile, and therefore escape easily through the finest openings and between the walls of valves of general construction, if same form part of adropping device. The liquid fluid chloroform, for instance-then not only falls in drops from the orifice of the device, but issues from the outsidefparts of the valve and is spent uselessly an wasted.

It is the object of this invention to avoid the described deficiencies and provide a novel chloroform-dropper which lssues the liquid fluid solely through the outflow-orifice of the dropper.

Owing to the construction of my novel dropper no leakage can occur and no chloroform is wasted.

The device is sim le in construction and can be manufacture cheaply The invention further conslsts 1n the con-- 7 struction of details and arrangements of parts.

It is illustrated in the accompanying drawin%s, in which v igure 1 represents in elevation a l1qu1dfluid dropper which embodies'my invention. Fig.2 illustrates, on an enlarged scale, in vertical section the upperpart of my device. Fig. 3 is a cross-section on line :10 a; of Fi%. 2 and Fig. 4 is a cross-section on line y y of ig. 2, the stopper havingbeen turned ninety deees. Similar'characters of reference denote like parts in all the figures.

My novel liquid-fluid drop er,consists, essentrally, of. a fluid-receptac e or bottle, a metal tube secured to the neck of said bottle and having a narrower upper ortion, which is threaded on the inside, an a compound metal stopiper adapted to be attached to the bottle an en .bodying my improvements. This stop er comprises elements for the ingress of an into the bottle, the outflow-of the liguid fluid, and a valve device which is a apted to c pen and tightly close the drop- In the dra ivin s, fluid reservoir or form fr r such devices. It is flat on one side and somewhat-bulged on the other. This form of bottle is convenient when it is desired to carry same in the ocket.- The neck I) of the bottle is provide on its upper portion witha metal tube 0, which is cemented thereto or otherwise secured. This metal tube has a narrow top portion 0', which is threaded on the inside.

The compound stopper consists of two parts, an inner lplart or plug cl, and an outer part or shell, w 'ch has a solid bottom ortion. The lower portion (1 of the plug is a solid metal rod circular in shape and of even diameter throughout. It has an enlarged rim d at the to which is roughened, ribbed, or knurled, so t at it may be tightly gripped. Asmall boring 6 passes through the plug, and a small tube f is attached to the to part of the plug, so that its opening coinci es with'the ormg e. The upper portion of the tube is bent outwardly and has an outflow, or' ce, or aperture at the end. The channel or boring e and the tube f form part of the passageway of the liquid fluid during the operation of the device. Asecond boring g, somewhat larger than the boring e, is provided in the In which connects with a second small tube also somewhat larger than the tube f, and

a represents the liquidbent outwardly at the tolp in the opposite di-' rection to said tube f. he boring g and the tube 71. coincide and form part of the passageway of the air, which rushes into the bottle when the device is used. In the center bottom portion of the plug there is a threaded opening adapted to receive a screw. A small pm '1'. is secured in the top portion .of the plu near the rim- (1 and at a right angle to the tubes f and h. I The outer part or shell of the compound stopper has a tubular top portion 1', which fits exactly over the lower portion d of the ottle, which is of the usual' IIC I Ul

plug (2, and an enlarged bottom portion n,

tion 0' of the tube 0 on the neck of the bottle.-

Two incisions .ls l are made on the to portion of the shell, in one of which rests t e pin-'-= 'L, as shown in Fig. 1. A leather washer o is provided on the threaded portion of the part 'n which tightens the bottle there. The solid part 1 has three b0rings .one in the center which serves for assing through a screw and coincides with t e central opening in the plug (1. The small boring e coincides with the boring e in the plug d, while'the larger boring g coincides with the larger boring g of said plug. A long tube 1? is secured to the part n corresponding to t e boling g and extending down to nearly the bottom of the bottle. This tube completes the passageway for the inrushing air. Thepassage-way for the liquid fluid is completed by the boring e. Within the tube jtand on the top of the art n there is a leather washer g, wlnch a'lso s three openings 2 g and a central one, which correspond to and coincide with the borings above described. This washer tightens thedevice completely. A screw r passes through the dplug 11. into the central opening of the-plug On the lower portion of the screw 1' there is a circular spring 8, which is held in position by the shoulder r of the screw 1', its upper end resting against the bottom surface of the art n. The spring 8 tends to. draw the plug tightly down upon the washer g, wherebg any leakage of the liquid fluid is prevente Assuming now-that the device is screwed together and in the osition shown in Figs. 1, 2, and 3, then same is open and ready for use. When the bottle is held'with its openings downward, then air rushes in through the tube It, the channels 9 and the long tube 1). At the same time the liquid fluid passes through the channels e e and the tube {1 and drops out through the orifice of the atter. N0 fluid-say chloroformcan escape, be-

causethe two parts forming the stop er are" held firml together by the screw 1' an spring 8 and the eather Washer q tightens them completely. When it is deslred to close the device, then the plug (1 is held firmly on the rim- (1 and turned around for about ninety degrees. The pin '2', of the plug (1, which originally was inthe incision 7c, is thereby transferred into the incision Z, where it stops. The channels e 9 have accordingly been ,removed and turned for about ninety degrees and no lon er co-' iy the masses device is closed. The plug d thus acts as the key of a valve, and thedistance ofthe openings in the channels from each other is rela tivel large, thus assuring the tight closing of the evice. The relative location of the upper and lower channels in the closed device is shown in 4.

Having t us described my invention, I claim as new and desire to secure by Letters Patent 1. A liquidfluid dropper comprising a fluid-receptacle, a compound stop er and valve consisting of an inner part or p ug with pin, and an outer shell having two incisions in Its top which said pin engages alternately and a solid bottom part, the two parts having coinciding channels, and two small tubes connecting one each with one coinciding set of channels, all so arranged that the location of the channels in the plug may be changed by turning it ninety degrees, whereby the dev1ce is opened and closed.

2. A chloroform dropper com rising a chloroform receptacle or bottle aving a metal tube secured to its neck, a compound stopper and valvemade in two parts having coinciding channels for the ingress of the air and the outflow of the chloroform, a leather washer with openings coinciding with said channels located between the two arts of the stopper, and a central pin wit spring adapted to force said two parts together, all so arranged that the location of the channels in the upper part may be changed b turning said part ninety degrees whereby t e device is opened and closed.

3. A chloroformdropper comprising a chloroform-bottle having a metal tube secured to its neck, a com ound stopper'and valve adapted to be joine tighlyto the bottle and made in two parts, aninner part or lug with pin and anouter shell havinga solid ottom part and two incisions in its topin which the pin of the plug locates alternately, both parts having coinciding channels for the i11 gress of the air and the outflow of the chloroform, a leather washer between the two parts of the stopper with openings coinciding with said channels, and a central pin with spring adapted to force said two parts together, all

so arranged that the location of the channels may be changed by turning said plug ninety degrees in a horizontal plane whereby the device is o 7 ened and closed.
